You're apparently trying to pass this parameter as an int4 ...
I thought only binary or text is allowed as parameters.
Guess I was wrong...
Thank you.

... but given that you didn't specify any data type, I think the
parser will fall back to assuming that $1 is the same type as
"abf_type", whatever that is. Passing data in binary is not at all
forgiving about getting the data type right.
